Patented Sept. 8, 1931 PATENT OFFICE SALVATORE A. TEN UTA, OF CHICAGO, ILLINOIS BUCKLE Application filed May 12,

My invention relates to buckles, and the general object is to produce a simple, inexpensively manufactured buckle which can be used for different purposes but which is designed particularly for application to suspenders for supportinggarments such as overalls.

More in detail, the object is to produce a simple buckle which can be stamped integral from sheet metal and which has a button-receiving opening and simple means for rigidly holding but for permitting easy and ready adjustment of a one-piece strap independently of any teeth or sharp points which might cut and fray the strap material.

Referring to the drawings- Figure 1 is a plan view of a buckle with the end of a strap applied thereto;

Figure 2 is a plan view of the buckle alone; Figure 3 is a section on plane III-III of Figure 1; and

Figure 4 is a section showing a modified form of the buckle.

The buckle shown comprises a rectangular body 10 with the extension 11 thereon for receiving a button. The base part 12 of the button-receiving opening is of a width sufficient to receive a button edgewise, and the opening contracts outwardly to form the outer part 13 for receiving the shank or stitching of a button, the throat 1 L between the opening parts being contracted so that the button shank or stitching will be more or less confined and held in order to retain the button to the buckle.

The body part 10 has three transversely extending slots 15, 16 and 17, the outer slot being somewhat wider, and these slots define the outer, intermediate and inner cross bars 18, 19 and 20, respectively.

I have shown the buckle applied to a onepiece suspender strap 21 which is threaded through the buckle slots.- Referring to Figure 3, the single strap is passed first through the outer'slot 15, then under the bars 19 and upwardly through the intermediate slot 16 and around the inner bar 20 and then under the intermediate bar 19 upwardly through the outer slot 15 and over the bar 18, the strap end E then extending a distance below the 1930. Serial No. 451,623.

body of the strap. The strap, when threaded through the buckle, is thus folded and looped around the inner crossbar 20, the upper fold A being above the lower fold B which terminates in the adjusting end E.

When the buckle is applied to a button, as in the case of suspenders, and tension is applied on the strap body 21, the fold A between the bars 18 and 20 will be straightened out or made taut and pressed against the fold B so that the fold B is clamped between the fold A and the bar 18. This frictional engagement of the folds together with the frictional engagement of the strap with the crossbars will rigidly hold the strap and buckle against relative movement while the strap is under tension without the aid of any othervstrap securing means.

If'it is desired to shorten the bod 21 of the strap, this can readil be done. y outwardly moving the said ody 21 and then inwardly and outwardly raising the fold B away from the fold A to move the buckle upwardly on the strap body a desirable distance, thereafter the upward pulling of the end E of the strap will move loop B to its normal position in contact with the loop A. After adjustment has been made and the strap body 21 is again put under tension, the folds A and B over the bar 18 will be moved back into secure frictional engagement, and the buckle will again be anchored to the strap body against movement. 7

Whenever it is desired to lengthen the body 21 of the strap, this can be done by outwardly moving the strap body 21 away from frictional engagement with the fold B adjacent the bar 18 and then outwardly sliding the buckle on the strap whereby the strap end E is moved toward the buckle the desired distance. i

In Figures 1 and 3, the end E of the strap be formed by a single die operation from sheet metal and which is devoid of sharp lacerating teeth or projections and which enables the loops of a single strap, by their inter-frictional engagement and frictional engagement with the buckle crossbars, to securely anchor the buckle to the strap body against displacement without any other strap securing means but which permlts ready adjustment thereof.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not desire to be limited in thepatent granted hereon other- Wise than necessitated by the prior art.

I claim as follows:

A buckle consisting of a single substantially fiat piece of sheet metal and adapted to be formed in a single stamping operation, said (piece of metal having a body part provide with an outer transverse slot, an intermediate transverse slot, and an inner transverse slot, the outer slot being of substantially greater width than the other slots, all of the slots being of equal length, said slots defining three parallel crossbars of equal Width and length with smooth surfaces, said crossbars being similarly dished in cross-section to present similarly directed curved surfaces, said buckle bein adapted to permit the ready threading of a strap therein reversely bent over said crossbars, and to securely retain the strap when it is drawn taut with reversely directed portions thereof entered in the outer slot.

In testimony whereof I have hereunto subscribed my name at Chicago, Cook County,

Illinois.
